Why does an arkose sandstone have more angular grains than a quartz?
The angular grains are probably due to the high feldspar content of the arkose rock. Unweathered feldspar from granite, the source rock of arkose, would be composed of crystals with sharply defined cleavage planes, and would have formed a more euhedral crystal shape compared to the rounded quartz grains that are present in quartz sandstones.
